SMOKE AND GAS CONSUMER.

- SPECIFICATION forming part of Letters Patent No. 239,517, dated March 29, 1881.

Application tiled September 20, 1880. (No model.)

To all whom it may concern:

Be it known that I, SAMUEL K. LETTER, of the city of Chicago, in the county of Cook, of the State of Illinois, have invented a new and useful Improvement in Smoke and Gas Consumers, of which the followingpis a specification, reference being had to the annexed drawings, forming a part thereof', which will enable others skilled in the art thereto pertainn g to make and use the same.

My invention pertains to a device attached to a cooking-stove, range, or other `stove or furnace, for the purpose of consuming the smoke and gas, and of perfecting the combustion of the fuel in the fire-box.

In the drawings, Figure lis a vertical crosssectional view of the tire-box and a portion of the upper smoke passage or flue ot' a cookingstove, and of my device attached thereto. Eig. 2 is a vertical longitudinal sectional view of the same,and Fig. 3 is a perspective exterior view of my device.

Letters and figures of like naine and kind refer to like parts in each of the figures of the drawings.

My said invention consists of a box or combustion-chamber, A, ofcastiron or other suitable metal or other material, of which the rear edge, a, and the two ends a a are provided with perforations e2, and the upper side, a3, and lower side, a4, incline divergently from the edge a to the open front or mouth of the chainber. The lower side, a4, is prolonged into a downward-curved lip, a5.

This device, when applied to a cooking-'stove or range, B, as shown in the drawings, is arranged horizontally in the center otl the upper smoke passage or flue, b', in the direct lineof draft, between the re-boxb and the line-pipe ofthe stove, (herein not shown,) in such a po# sition that the lip a5 laps over and downward upon theback re-walhbz, ofthe tre-box, and that the upper side, a3, is against the top plate, b3, of thestove, to which it is in any suitable manner secured. r

The device being vthus constructed and arranged within the stove, the `smoke and gas, being drawn into the combustion -chanlber against the hot metal and through the perforations, are superheated and perfectly consumed.

Having thus described the said device, what I claim as new, as my invention, and desire to secure by Letters Patent, is-

1. In combination with a cooking stove, range, or other stove or furnace, a combustion box or chamber, A, provided with perforations a2, or their equivalent, iu the rear edge, a, and ends a a, substantially as described, for the purposes set forth.

2. In combination with a cooking l stove, range, or other stove or furnace, a combustion box or chamber, A, having divergentlyinclined sides a3 and a, and perforations a2 in the rear edge, a, and ends a. a', substantially 'as described, for the purposes set forth.

3. In combination with a cooking-stove, range, Vor other stove or furnace, a combustion box or chamber,A, having perforations a2 in the rear edge, a, and ends a. a', and the downward-projecting lip a5 of the lower side, c4,substantially as described, for the purposes set forth.

In witness whereof I heieunto set my hand this 16th day of September, A. D. 1880.
